3 Claims. (Cl. 140-105) This invention relates to a machine for cuttingand forming a stock material and particularly, to apparatus capable ofhandling wire mesh and of forming kinks in the cross-wires thereof asthe material is advanced along a support and ultimately wound on atake-up reel.

It is the most important object of the instant invention to provideapparatus of the aforementioned character that includes a plurality offorming Wheels cooperable with longitudinal slots in a supporting tableto automatically kink the cross-wires of wire mesh as the latter isadvanced along the table.

Another very important object of the instant invention is to provide ina kinking machine cooperating rollers for advancing the stock materialand having intermeshing tongue and groove structure for receiving thecross-wires within the kinks thereof, thereby providing for positiveadvancement for the purposes aforementioned.

Other objects include the way in which one of the slots of the tablereceives a severing disc to bisect the advancing material as it is beingkinked; the way in which the forming wheels are rendered adjustable by aspecial mounting permitting movement of the wheels into and out of theslots; the manner of driving the advancing rollers, as well as rollermeans to unroll the stock material from one end of the machine; the wayin which the wheels are staggered so as to produce proper results; andthe manner of adjustably mounting the cutter disc to accommodate forwear.

In the drawings:

Figure 1 is a side elevational view of a cutting and forming apparatusfor rolled stock made pursuant to the instant invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is an enlarged, fragmentary, detailed, crosssectional view takenon line III-III of Fig. 2.

Fig. 4 is an enlarged, fragmentary, detailed, crosssectional view takenon line IVIV of Fig. 2.

Fig. 5 is a fragmentary, perspective view of a portion of the stockmaterial after kinking and severance; and

Fig. 6 is a transverse, cross-sectional view through a pipe showing oneapplication of the kinked material.

A suitable support broadly designated by the numeral 10 mounts anelongated, horizontal table 12, composed of a plurality oflongitudinally extending plates 14 spaced apart to provide slots 16extending the full length of the table 12. Suitable notched standards 18are provided at one end of the support It) for rotatably receiving aroll 26 of stock material 22 to be kinked and severed through use of theapparatus forming the subject matter of the instant invention. 1

The wire mesh material 22 is of conventional character and includes aplurality of longitudinal wires 24 intersected by interconnectingcross-wires 26, the apparatus being capable of forming kinks 28 incertain of the crosswires 26 as best seen in Fig. 5.

The material 22 is unrolled and directed to the upper surface of table12 by means of a pair of rollers 30 and 32 carried by the support 10, atleast one of which (roller 32) is preferably driven through the mediumof a continuous chain or the like 34. The material 22 extends betweenthe rollers 30 and 32 as well as between a pair of rollers 36 and 38 atthe opposite end of the support 10 which serve to advance the material22 along the upper surface of table 12.

Roller 33 is also driven by the continuous chain 34 and the roller 36 isdriven in the opposite direction by virtue of intermeshing gears 40 and42 on rollers 36 and 355 respectively. A prime mover such as an electricmotor 44, carried by the support 10 beneath the table 12 is operablycoupled with the continuous chain 34 through a speed reducer 46 and anadjustable idler 48 is used to maintain the chain 34 in a tautcondition.

A plurality of freely rotating forming wheels 50 are disposed forcooperation with the slots 16 to produce the kinks 23 in the cross-wires26 automatically as the material 22 is advanced along the table 12. Thewheels 50 are staggered in a suitable manner as is illustrated in Fig. 2of the drawings, there being at least one wheel 50 for each slot 16respectively.

In the arrangement chosen for illustration, two wheels 50 are providedfor each slot 16 and they are mounted for rotation within yokes 52 thatare in turn provided with upstanding, externally threaded stems 54.Stems 54 extend through bights 56 of U-shaped brackets 58 mounted on thesupport 10. Opposed nuts 60 on the stems 54 hold the wheels 5% inselected positions extending into their corresponding slots 16 as bestseen in Fig. 3.

In order to provide for positive advancement of the material 22 alongthe table 12 without undue slippage, roller 36 is provided with annularribs 62 and the roller 38 is provided with corresponding grooves 64 asshown best in Fig. 4 of the drawings. It is noted that the ribs 62extend into the grooves 64 and that the same are disposed to receive thekinks 28 formed in the crosswires 26 by the plurality of forming wheels50.

As the material 22 is thus advanced and kinked, it is bisectedlongitudinally by means of a cutter disc 66 extending upwardly throughslot 68 in the table 12 so as to sever the cross-wires 26, preferablymidway between the ends of the latter. Cutter disc 66 is driven by aprime mover 70 such as an electric motor, carried by the support 10beneath the disc 66 and operably coupled with the latter by belt andpulley means broadly designated by the numeral 72.

In order to accommodate for wear in the disc 66 and thereby extend theuseful life thereof, disc 66 is mounted for vertical reciprocation on astandard 74 forming a part of the support ill and spring-loaded idlermeans 76, swingably carried by the standard 74, maintains the belt ofassembly 72 taut in all adjusted positions of the disc 66.

A take-up reel 78 rotatably carried by notched standards 86 mounted onthe support 10, receives the kinked material 22 and may be rotated byuse of a manual crank 82.

When the two rolls of kinked material 22 are removed from the take-upreel 78, they may be placed in use for various purposes and by way ofexample, Fig. 6 of the drawings illustrates the way in which acementitious coating 84 on a pipe 86 may be reinforced thereby.Underground pipes 36 are conventionally protected with a coating 83 ofasbestos or the like, and oftentimes the ciating 88 is in turn wrappedwith a paper-like material 9 Some soil and terrain conditions requirethe additional placement of cementitious coating 84 and in accordancewith the principles of the instant invention, the kinked material 22 isfirst wrapped over the coating 88 or the covering 9 if the latter isused. It is notable in Fig. 6

of the drawings, that when the kinked material 22 is spirally orotherwise wound on the pipe 86, the kinks 28 hold the same, particularlythe longitudinal wires 24, spaced away from the covering 90 so as toproperly receive and reinforce the cementitious coating 84. After suchreinforcement is tied or otherwise secured in place, coating 84 may beplaced thereon through use of conventional equipment that includes a gunnozzle 92 for spraying the material 84 on the pipe 86 until the kinkedwire mesh is completely embedded therein.

Many other advantages will emanate from use of the cutting and formingmachine above described and, therefore, it is desired to be limited onlyby the spirit of the invention as defined by the scope of the appendedclaims.

Having thus described the invention what is claimed as new and desiredto be secured by Letters Patent is:
